AUTOMATICALLY-CONTROLLED SHUTTER FOR MESURING: MACHINES.

Application led March 30, 192.2. Serial No. 547,954.

This invention relates to measuring and computing machines ot the type in which an indicating member is used which bears computed numbers which correspond to, or are tunctions ot' the measured length. The invention is especially applicable to a machine ot this general type for measuring and computing the cost ot' fabric. In such a machine the computed numbers on the indicating'` member do not necessarily Correspond to all the measurements Which the machine is capable of making. For example, the coniputed numbers may correspond to all measurements increasing by an eighth of a yard, While the machine is capable of measuring inches.

The general object of the invention is to provide a shutter the reading point of the machine vwhich will operate to prevent reading the computed number unless it is accurately presented at the reading point, as a consequence ot Which the machine would indicate precisely the length to which the computed number corresponds; and to provide such a machine with hand-operated and au* tomatic means for opening the shutter; and to provide a marking device for marking the fabric at the point Where it is to be cut ofi,

which operates automatically to open the shutter it the computed number is accurately alignedwith the reading point; and also tov provide means whereby the marking means may be operated in any measuring position ot the indicator, Without necessarily actuating the shutter, enabling the machine to be used to measure and cut any length desired and measured in inches Whether the measurement is commensurable in eighths ot a yard or not; also to provide automatic means for holding the shutter open after it has been opened by the actuation of the marking means, and for automatically etiecting the closing of the shut-ter When the indicating mechanism ot the machine is reset to Zero; and to provisie a. construction that will enable the shutter to be opened at Will by handk position or the chart and Without the shutter in its open position.

er objects of the invention Will appear hereinafter.

T he invention consists in the novel `teatures, and in the general combination ot parts to be particularly described hereinci, all of Which contribute to produce a simple and cticient automatically controlled shutter for measuring machines. A preterredv embodiment of our invention Will be particularly described in they foliowing specification, While' the broad scope of our invention will be pointed out in the appended claims. v

Figure is a vertical section'on the line 7-7 Fig. 2. showing a' detail of the means torautomaticaliy controlling the shutter by the resetting mechanism.

Figure 8 is a vertical section taken on the line 8 8 ot Figure l and particularly illustrating the hand-operated means for opening the shutterindependently of the automaticy means. I In the machine illustrated l represents a casing provided with anv indicating member which may be in the term oi'Iv tivo charts 2a and 2b supported in the upper part of the trame 3 of the machine so as to enable them to present computed numbers i atA 'he reading point, or reading points oie the machine.

In the present instance these numbers 4 are disposed in rows which are presented in succession at tivo Windows 5 and 6 Which. constitute the reading' points for the machine. These Windows 5 and 6are provided with scales 7 and 8, respectively, which carry numbers indicating ditierent price rates, and the computed numbers or' xix the chart indicate the charge to be made tor the quantity measured at any of the price rates indicated on the scales.

Means is provided on the charts for indicating the length measured. Referring to F igr e 1 the numher 2% near the lower edge ot the chart as viewed by the operator at the lett oit the matnine shows that the machine is now indicating a measurement oi 2% yards. ln addition to this indicating means we also provide length indicating means including dial 9 in the upper portion ot the casing, and provided with a laet moving pointer 10 and a siow moving pointer 11, the Yformer ot which co-operates with the small numbers 12 ot the dial scale which indicate inches; the pointer 11 cooperates with the large numbers ot the scale which indicate yards. ylfhe scale on the uial also includes numbers indicating fractions oit a yard increasing by eighths. The pointer 10 makes one complete revolution in measuring a. yard while the pointer 11 is cooperating with the large numbers to indicate a measurement of one yard.

TWhen the machine is in operation the iabric is pulled hetween a measuring roller 13 (see Figure et). and a presser roller 14e which is then pressed down upon the measuring roller. The rotation of the measuring roller 13 is imparted to the indicating n'ienjibers or charts 2a and 2b and also to the indicating pointers 10 and 11. Any suitable gear train may be provided 'tor this purpose. such as that indicated in Figures 2 and 4l, in which the shaft 15 oi" the measuring roller is provided with a pinion 16 driving a gear wheel 17,` the same being provided with a friction clutch 18; the driven member 18 ot this clutch is rigid with a pinion 19 which mes ies with a large gear 20 secured t one end ot a horizontal arbor 21, the inner end ot which is supported in a vertical trame plate to the trame plate 22 carries a pinion 23 which meshes with a gear 23L which in turn meshes with two gear wheels 24; and 25, respectively, the shafts 26 and 27 of which carry take-up rollers 2S and 29 upon which the charts 2a and 2b wind. TWhen the charts are in the Zero position they are wound in coils on a supply roller or drum 30 (see Figure 3).

In order to drive the hands 10 and 11, the arbor 21 is provided with a bevel gear 31 which. drives a bevel gear 32 on the lower end oi a tubular sha'tt 33 (see Figure G). This tubular shaft carries the ast'moving pointer 10 and operates through a reduce tion 311 `(see Figure 1) to drive'the slow moving pointer 11 at its proper speed. 'Ehe reduction gear may be oit any suitable type. We have illustrated the simple reduction gear of the oscillating type involving the use of an eccentric 35 on the tubular The'end oi' this arbor 21 adjacent shaift 33 which is rotatably mounted in an Y opening in an oscillating gear wheel 36, the teeth ot which 'mesh with the teeth of a crown wheel 37 which isrigidly secured to au outer tubular shaft 38 carrying rigidly the slow moving pointer 11. The oscillatis prevented iroin Vrotating by an arm 3Q attached to it and which is guider to move in a radial direction by means ot a slide Il() in its outer rend engaging a reduced neck on a stanchion or post 411 which torms part olf the trame.

through a .slot- L16 (see Fig. rithe lever a l-:ni'te 4f? which cooperates with knilfe 113 to mark the fabric after it in applying our invention to such a machine we provide a shutter device including two rotary shutters 49 and 50 (see Figs. 1 and. i?) and we provide automatic means actuated by the movement ot some part of the machine 'f' making the measurement, which oies to open the shutters. For this purpose7 the shutters arerotatably mounted en the sha't'ts and 27 oi' the. take-up rollw's 28 and 29 and adjacent to the 'trame plate they are connected together by a link 51. (see ,liigure 1). The pin 52 which attaches the link 51 to the shutterlQ ralso air'ords means '.torattaching a link 53 which is actuated by an arm 5&1 mounted on a shaft 5 in tie 'l' ame plate 22 and passing' to the L side oi the trame plate. We provide *or rotating the shaft 55 when a part such as the marking lever is operated after the measurement made, `:but we also provide means tor preventing the opening movement oi the shutter unless two ot the rows of the computed numbers l on the charts are proporly aligned at the reading points or windows 5 and 6. 4

1n order to accomplish this we provide the rock shaft 55 with av lever plate 56 which may he ollv substantially triangular form (see Eig. 2), the outer portion et the plate being pivotally attached by a pivot screw 57 to aslide 53 idcd to movein a vertical direction on the tace ot the traine plate 22. le coiled spring 59 is attached end oil this slide and the function ot this spring is to return slide 53 'iter actua by the marking means. ifi/Te provide connection om the shai't- 413 to this slide for pulling the slide down and thereby actuating the rock shaft 55 to open the shutters, and this connection includes a link GO lyingv on the outer face or the slide 58 and conto the upper i ie machine includes marking means tor .irovided with a thumbeplate 15 which is `osed on the exterior oi' the casing Eil nected to the slide by a pin 61 and slot 62, the pin being secured in the slide. A spring 63 is provided, the lower end of which is attached to the link and the upper end attached to the pin 61. `Hence, if the link is pulled downwardly it will exert a downward pull through the spring 63 upon the slide, the downward movement of the link being permitted by the slot 62. The link will be pulled down by the rotation of the shaft 43-by reason of the fact that the shaft 43 has a pin 64; received in a slot 65 in a dog 66, (see Figure et) which is pivotally mounted at 6.7 on a bracket 68 mounted on the base plate 4:4. The end of this dog is received in slot 69 formed in the lower end -of the link for actuating the link by the dog.

ille prefer to hold the shutters open after the link 60 has pulled the slide 58 down,

by tletent means such as a detcnt .pawl 70' which may be pivotally mounted at 71 near the vertical face of the frame plate 22 so as to co-operate with a detent tooth 7 2 which projects from the edge of theslide (see .Figure 2). This detent pawl is moved into its engaging position by a spring 73.

The shaft Li3 is located just below the pivot or shaft 42a of the lever 4t2. Just below the lever pivot 42a the lower edge of thY lever Ll2 is provided with a notch 75 which co-opcrates with a dog 't6 which proiects up from a collar 77 rigidly attached to the shaft e3 (see Figures 2 and 4)..

Referring; to Figure a it will loe evident that when the lever l2 is depressed the. dog 66 will also be depressed and this willmove the link 60 to open the shutters.v Vhen the link is moved in this way the detentfpawl or latch 70 will operate to hold the shutters onen. The slide 58 is guided on the frame plate 22 by means of a screw 78 Vthe shank of which passes through a slot 79 in the slide, i

the head of the screw being received in the large slot 8O formed in the link 60.

The ine-sns for preventing the operation of vthe knife lever from opening the shutters unless the numbers 4l of the charts are propcrlv aligned includes a locking device 81 w ch in the form of a disk having one or more notches S2 in its edge.y and this disk is driven in synchrony with the. charts bv means of a pinion 33 carried on its shaft,

which pinion meshes with the large gear wheel 20, already described (see Figure 2). The gears 2O and 83 are of such a ratio that this disk S1 will make one-half of a revolution for every eighth of a yard of advance of the charts. And whenever one of the rows (which correspond to a length cominensurable in eighths of a yard) lies opposite its reading point, -then one. of the notches 82 will be presented opposite to a pin S41- which projects out from the face of the rocking plate 56. If the length Vindicorresponding computed numbers on the indicating members, or charts, then the movement of he pin 84 will be obstructed by the disk 81 and the shutters will not open, but

by reason of the flexible connection of the spring 63, the operation of the knife lever will not be prevented. This enables the inachine to be used for n'ieasuring andL cutting any quantity which the machine is capable of measuring. If ythe quantity measured is commensurable in eighths of a yard the shutters will open automatically to show the operator what charge should be made forl the amount cut 0H.

)Ve provide automatic means for effecting the closing-of the shutters, assuming that they have been opened by the operation of the knife lever. In the present instance we effect this simply by releasing the detent pawl 7() automatically by the resetting movement. In this machine the resetting of the indicating mechanism to zero is effected by means of a coil spring 85 within the drum 30 (see Figure This spring will operate to return the indicating mechanism to zero if the clutch 18 is opened, and the resetting is effected by opening the clutch by pressing the outer end of the clutch stein 86 (see Figure 4:). This is elected by means of a lever S7 which is actuated by means of a handactuated resetting member or button 88 which is exposed on the exterior of thecasing (see Figure 5). This resetting member has aV flat stem 89 guided to slide through a suitable bracket 90, andbeyond the bracket is provided with a linkr91- which extends `downwardly and has a pivotal connection with the lower end ofthe lever 87. The `inner end of the stem 89 is guided by means of afslot 92 onl a pin 93 carried on the leva' 87. In order to enable this resetting member to release the pawl 70 we provide the shaft 43 with a loose rocker 94 which is in the form of a bell crank lever (see Figure 7) one arm 95 of which projects over so as to engage the upper side of a horizontal arm 70 which operates as a taill for the pawl 76. The bell crank lever 94 has an upwardly eXn tending arm terminating in a push plate 96 which is directly in line with an extension 91"L which forms the forward end of the aforesaid link 91. The clutch member 18a referred to above is carried by vtherstem 86 so that when the thumb-plate 88 is shoved in the clutch will be opened. Vhen theclutch is opened the spring 85 will return the indicating mechanism to Zero; at the same time the forward end of the link 91 will operate through the bell-crank lever 94 to release the pawl 70, and the shutter spring will then movement.

pendently oiE the marking means. In order to enable this to be accomplished we provide a handbperated member or push but ton 97, the stem of which pass-es vertically downward through the upper wall oi'l the casing 1 (see Figure 8). `his push-button is connected in any suitable manner with the aforesaid link 53 which is actuated by the member or arm d controlled by the operation oi the marking means 12. ln order to enable either the arm 5d or the push-button 97 to actuate this link we provide a lostmotion connection between the arm and the link consisting ot a pin 98 on the arm and a slot 99 in the link. The push-button 97 operates thelink through a bell crank lever 100 the vertical arm 101 of which has a slot receiving a pin 102 on the end of the link. A spring A elevated position after it has been actuated and also return-s the shutters to their closed position after the push button is released.

We shall now describe the general mode of operation ot the entire ina/chine.

By pulling the fabric to be n'ieasured through the machin-e the nieasuring roller 13 is rotated and by reason ol its pinion 16 the movement is imparted tlirougli the gear train including the large gear (see Fig ure 2) so as to ell'ect the rotation ot the gear wheels 2d and 25. This ellects the rotation oi' the takeeup rollers 2S and Q9 and winds the charts 5 and G oil ot the drum 30. rThe spring' 85 (see Figure 3) maintains the charts taut. When the desired amount oit fabric has been measured oli" the operator presses down on the tl'iuinb-plate .d5 which operates the'marking lever 12. This notches the edge of the arbric at the point where it is to be cut olin through the medium oi' the blades Li7 and d8.

The measuring movement is imparted to the pointers 10 and 11 on the measuring dial 9 through the bevel gears 31 and 32 and through the reduction gear 3d.

he operation ol.: the kniife lever also actuales the shaft i3 which, through the dog 66 elilects the downward movement of the link 60. rlliis downward movement is imparted through the coil spring 63 to the slide 58, and this moves the rocker plate 56 and rocks the rock-shalt Through the link 53 this roel; shaft opens the shutters. The downward movement ot the slide 5S brings the detent tooth T2 down so that the spring 73 causes a. latch or detent pawl to engage the tooth 72 and this will hold the shutters open so Vas to expose the reading points on the charts. rlhe shutters will open in the manner described il the machine is indicating a length commensurable in eighths ot a yard because that time one of the notches 82 will be opposite to the pin 842 and this will permit the rocking plate 56 to have tree It the machine is not indicat 103 returns this push-button to its ing a vmeasurement coinmensurable in eighths of a yard no row ot numbers on the charts will be aligned at vthe reading points, and hence neither of the notches 82 will be opposite the pin Sil. rlhe disk 81 would then prevent the swinging of the rock plate and hence would prevent opening of the shutters. rlhis action ot the disk 81, however, would not interfere in any way with the operation yof the knife because the springs (i3 would simply be extended by the action of ther shalt l5 and dog 66 without moving the rocker plate. rfhis mode of operation oermits the machine to be used for meas ng and cutting oli any of the intermediate lengths indicated by the mechanism, but not having corresponding computed numbers,lifor example, seven inches.

lVlien the indicating mechanism is to be returned to zero the resetting member 88 is pushed inwardly and this operates through vie lever 8?' to actuate the stem 86 of the hitch 18. nd mechanism to Zero. The 'forward end ot the link 91 also actuates the rocker 94, the arm et which pi sees the tail 70a of the detent pawl 70 (see gure 7). YThis releases the pawl and permits the shutter spring 59 to close the shutters.

lt it is desired to open the shutter with out operating the marking means 12 this can rllhis opens the spring clutch 18 l spring then resets the indicatingV be accomplished simply by depressing the push button 97. rlhis will rock the bell crank and thereby exert a pull in the link 53 which will open the shutters. As

soon as the push button is released theV spring 103 will pull the shutter closed and also return the push button to its elevated position. y i
